security_policy Keyword

You can use the security_policy keyword in your sysidcfg file to configure your system to use the Kerberos network
authentication protocol. If you want to configure the system to use Kerberos,
use the following syntax.

FQDN specifies the fully qualified domain
name of the Kerberos default realm, the administration server, or key distribution
center (KDC). You must specify at least one, but no more than three, key distribution
centers.

If you do not want to set the security policy for the system, set security_policy=NONE.
